"We are obviously extraordinarily relieved," Obama said of Ling and Lee's return. "The reunion that we've all seen on television I think is a source of happiness not only for the families but for the entire country."

"I want to thank President Bill Clinton -- I had a chance to talk to him -- for the extraordinary humanitarian effort that resulted in the release of the two journalists," Obama said.

"I think that not only is this White House obviously extraordinarily happy, but all Americans should be grateful to both former President Clinton and Vice President Gore for their extraordinary work," the president added. "And my hope is, is that the families that have been reunited can enjoy the next several days and weeks, understanding that because of the efforts of President Clinton and Gore, they are able to be with each other once again."
